GAS-GENERATOR.

Specification of Letters Patent.

Patented Sept. 11, 1906.

Application filed June 7, 1905- Serial No. 264,173.

To all whom it may concern:

Be it known that I, IVILLIAM HENRY CONE, of the town of Berlin, in thecounty of VVaterloo, in the Province of Ontario, Canada, have inventedcertain new and useful Improvements in Gas-Generators, of which thefollowing is a specification.

My invention relates to improvements in gas-producing generators; andthe object of the invention is to produce a fire-pot bottom which willhold the fuel up in the center, and so produce an equilibrium of heat inthe side and center. To carry out this object, I have constructed andarranged my fire-pot bottom in the generator, as hereinafter moreparticularly explained.

The orawing represents a sectional perspective view of a lower portionof my generator, showing my improvement.

A is the casing of my gas-generator, which is preferably cylindrical inform and is provided for the major portion of its height with afirebrick lining A, surrounding the firebed, and peep-holes A so thatthe operator may be able to see the condition of the fire-bed.

A is a ring forming the bottom of the firebrick.

A is an internal casing forming the lower portion of the firebedthat is,the portion in which the ash falls. The casing A is proviced with anoutwardly-extending flange A which is supported on an annular angle-ironring A. The flange A has an upwardly-extending portion next the casingand forms an annular space around such casing and beneath thefire-brick. B represents a series of holes arranged in a circle andcommunicating with such annular space. The sizes of the openings of theholes B are controlled by a ring O, having a series of holes C, whichare designed to register or partly register with the holes B, or thering may be moved to entirely close the holes B. The means of turningthe ring 0 is a handle C which is suitably connected to the ring andextends out through a slot in the side of the casing. These openings aredesigned for a purpose which will hereinafter appear.

D is the stationary bottom of the fire-pot, which is conical in form andprovided with a projecting central portion D, which is hollow andextends in the form of a conduit down below the conical bottom andlaterally to the casing, as shownat D having connected thereto asuitable flange-pipe D provided with a damper D".

D is a pipe or conduit leading from the annular space surrounding theash-bed to the conduit D E is a conical grate, which surmounts thebottom D and is provided with a handle E, by which such gratev isshaken. It will be noticed that there is a space between the bottom ofthe internal casing A and the bottom edge of the grate to facilitate thedischarge of the ashes.

The top of the conduit D is closed by means of a valve F, supported on acentral stem F, having an eccentric end F through which extends thelaterally-extending stem F, operated by a handle F It will now be seenby means of the handle F" the position of the valve F may be regulated,so as to allow of more or less of a draft through the center of thefire-bed, depending upon the condition of the bed as to incandescence.

By the form of my supportingbottom for the fire-bed the center of thefire-bed is, I find, kept substantially level instead of subsiding, asis usual in other forms of grates or fire-bed bottoms of which I amaware. I am also enabled, as hereinbefore described, to keep the bed ofthe fire level by means of the raised center of the bottom for thefire-bed and by changing the drafts of steam-laden air from center toside, or vice versa. I am also enabled to produce an equilibrium of heatfrom center to side and prevent airchannels from forming in the body ofthe fuel at the side and the deterioration in the quality of the gasproduced.

I/Vhat I claim as my invention is 1. In a gas-generator, a fire-potbottom of conical form extending from substantially the centerdownwardly to the edge and leaving an edge opening underneath thefire-pot and a correspondingly-formed shaking-grate superimposed on thebottom and provided with a suitable shaking-handle as and for thepurpose specified.

2. In a gas-generator, a fire-pot bottom of conical form having asubstantially cylindrical raised projection in the center, said Iprojection having an opening therein and a valve for controlling saidopening.

3. In a gas-generator, the combination downwardly through thepassage-way and means for raising and lowering the stem as and for thepurpose specified.

5. In a gas-generator, the combination with a fire-pot bottom having araised proj ection and a central air passage-way extending therethrough,of a valve extending over the central projection and passage-way, a

stem supporting such valve and extending downwardly through thepassage-way, and provided with an eccentrically-formed lower end and arod extendingtherethrough and provided with a handle outside the casingas and for the purpose specified;

6. The combination with the bottom of the fire-pot having a raisedcentral portion and a vertical passage-way extending through suchcentral portion of a conduit leading from such passage-way laterallyoutside the casing, a valve to close the top of the passage-way, andmeans for raising and low- 1eiring the valve as and for the purposespeci- 7. In a gas-generator, the combination with the fire-pot andcasing surrounding the bottom of the same, an annular chambersurrounding the casing and communicating therewith through holes in thecasing, and with a source of steam and air-supply, of a bottom for thefire-pot provided with a raised center and passage-way therethrough andcommunicating with the annular chamher, a valve covering the top of thepassageway and conduit extending through the raised center and means forcontrolling the valve as and for the purpose specified.

8. In a gas-generator, the combination with the casing and fire-bricklining for the fire-pot, of a casing forming the lower portion of thefire-pot and having a series of holes arranged around the upper portionthereof and provided with an outwardly-extending flange forming beneaththe firebrick an annular chamber opposite the holes,

.a steam and air supply in communication with the annular chamber and aring provided with a series of holes correspondingly formed and arrangedto the holes of the casing, and means for circumferentially adjustingthe ring as and for the purpose specified.

9. In a gas-generator, the combination with the casing and fire-bricklining for the fire-pot, of a casing forming the lower por-.

tion of the fire-pot and having a series of holes arranged around theupper portion thereof and provided with an outwardly-extending flangeforming beneath the firebrick an annular chamber opposite the holes, asteam and air supply in communication with the annular chamber, a ringprovided with a series of holes correspondingly formed and arranged tothe holes in the casing, ;means for circumferentially adjusting the ringand a firepot bottom provided with a raised center and passage-wayextending through the raised center and communicating with the annularchamber aforesaid, and

a suitable valve located above the raised center and passage-way andmeans for controlling such valve as and for the purpose specified.
